I am trying to fit data from a simulation to a polynomial. Luckily I do know the exact data and I know that my values are not bad at all!
However, when trying to fit the data to a polynomial function ...

The pdf of a standard Gamma distribution is $f(x) = \frac{x^{\gamma-1} \exp(-x)}{\Gamma(\gamma)}$. How do I find the pdf of of the random variable Z = X + Y where Y is the Normal distribution? There ...

Here is a great example of the implementation of HMAC MD5 and SHA in Mathematica:

Can anybody explain how to modify that ...

Tell me please, how on the 2-nd step of algorithm to find intervals (where roots exist) separately in the 1-st found interval {2.11731,3.3125} and in the second {5.5,5.75}, using myintervals1 ???? I ...

Help me please to fix the line!
The line "For.." works and prints intervals which don't contain roots.
And I have to output the remaining intervals which include roots. (I know that these intervals ...

I'm having problems to plot two functions, which I called: gama[t_], mgama[t]. And I want to calculate NIntegrate[{mgama[t]}, {t, 0, 20}], but it's giving error.

I have a problem with handling my dataset in Mathematica. Basically, I just want to create a new column "newColumn" which depends on 2 other columns, "a" and "b". But the values in "a" can either be x ...

It's been nearly ten years since I took my DSA class. I've looked through Wikipedia's list of sorting algorithms but none stand out as being this one. It's part of a priority queue implementation, and ...

I am trying to use Animate in conjunction with Graphics3D to make a list of vectors that have oscillating lengths. Basically, a list of random 3D vectors are plotted originating from the origin. Then ...

So, this may be a question that requires knowledge of both Mathematica and R -- a fairly small set of people, but I am giving it a try. Suppose I use Mathematica's LibraryGenerate function to create ...

I recently downloaded Wolfram Mathematica 10 and am running it on Windows 8.
I tried to use the drawing tools to add some points on a graph, but every time I change the color in the settings for the ...

I am solving a project in Mathematica 10 and I think that the best way to do it is using a loop like For or Do. After build it I obtain the results I looking for but with a to much big multiplicity. ...

Something is wrong with this PRNG, it uses a large (65536 bit) pool of bits from which randomness is extracted in sets of 256 bits, what seems to fail is the bit storage feature (ests,sts,lts,elts) ...
